步骤:
1.在pom.xml中添加插件配置
<plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.5</version> <dependencies> <dependency> <groupId> mysql</groupId> <artifactId> mysql-connector-java</artifactId> <version> 5.1.39</version> </dependency> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.5</version> </dependency> </dependencies> <executions> <execution> <id>Generate MyBatis Artifacts</id> <phase>package</phase> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <!--允许移动生成的文件 --> <verbose>true</verbose> <!-- 是否覆盖 --> <overwrite>true</overwrite> <!-- 自动生成的配置 --> <configurationFile> src/main/resources/mybatis-generator.xml</configurationFile> </configuration> </plugin>
2.在resources文件夹中添加mybatis-generator.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true"/> <property name="suppressAllComments" value="true"/> </commentGenerator> <!--数据库链接地址账号密码--> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1:3306/longhubang" userId="root" password="hongda$123456"> </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> <!--生成Model类存放位置--> <javaModelGenerator targetPackage="com.example.scheduleService.model" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator> <!--生成映射文件存放位置--> <sqlMapGenerator targetPackage="com.example.scheduleService.mapper" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!--生成Dao类存放位置--> <!-- 客户端代码,生成易于使用的针对Model对象和XML配置文件 的代码 type="ANNOTATEDMAPPER",生成Java Model 和基于注解的Mapper对象 type="MIXEDMAPPER",生成基于注解的Java Model 和相应的Mapper对象 type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口 --> <javaClientGenerator type="ANNOTATEDMAPPER" targetPackage="com.example.scheduleService.dao" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> </javaClientGenerator> <!--生成对应表及类名--> <!--<table tableName="stocktradeinfo" domainObjectName="StockTradeInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>--> <table tableName="theme" domainObjectName="Theme" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> <table tableName="stockTheme" domainObjectName="StockTheme" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> </context> </generatorConfiguration>
3.根据配置创建对应的model,mapper,dao文件夹
4.使用maven中的mybatis-generator:generate根据数据库里面表生产相关的类,Mapper
注意:
这里面自动生产的Mapper
1.没有@Mapper注解
2.在insert的时候会带上主键ID
